What is Data Com­mu­ni­ca­ti­on?

-

A key aspect of data com­mu­ni­ca­ti­on is under­stan­ding your tar­get audi­ence and crea­ting visu­als that com­mu­ni­ca­te infor­ma­ti­on in a cap­ti­vat­ing man­ner. Effec­ti­ve data com­mu­ni­ca­ti­on include using the right words to con­vey the infor­ma­ti­on.

Data com­mu­ni­ca­ti­on refers to the trans­fer of data from one com­pu­ter to the other via the inter­net, or through any other method. Infor­ma­ti­on can ran­ge from a simp­le audio file to a text mes­sa­ge. The medi­um used to trans­mit data could be wire­less or wired. To allow two com­pu­ters to com­mu­ni­ca­te with one other, they need an opti­on of lin­king which is known as a chan­nel or chan­nel.

Modern net­works for data com­mu­ni­ca­ti­ons employ dif­fe­rent data trans­mis­si­on chan­nels. They include sim­plex, duplex and full-duplex. Sim­plex mode allows infor­ma­ti­on to flow only in one direc­tion, whe­re­as duplex mode allows the sen­der and recei­ver both to trans­mit simul­ta­neous­ly. Full-duplex is simi­lar to duplex, howe­ver it requi­res that both recei­ver and trans­mit­ter are syn­chro­ni­zed to read the bina­ry data bits in the signal being trans­mit­ted.

The data that is sent over a data com­mu­ni­ca­ti­on chan­nel can be eit­her digi­tal mes­sa­ges that are sent by a micro­pro­ces­sor or an ana­log signal, such as a tele­pho­ne call or video foo­ta­ge that has been digi­ta­li­zed into a sequence of bina­ry bits using pul­se-code modu­la­ti­on. Any errors in the trans­mis­si­on data should be iden­ti­fied and cor­rec­ted to ensu­re that only the cor­rect infor­ma­ti­on is recei­ved by the recei­ver at the other end. This is usual­ly accom­plished by using a com­bi­na­ti­on sequence https://bigdataroom.net/adobe-premiere-pro-for-free-or-creative-cloud/ num­bers and ack­now­led­ge­ment codes.
